[0043] In addition, the elastic clamp (84), formed with gripping teeth (82) that protrude and are bent in a corresponding manner to grip the head of the bolt on the clamp part (80), is formed in a corresponding manner on one end of a steel hollow tube (88) made of a hollow material of a certain length, and is formed in two or more according to the design and the needs of the operator so that the clamping function can be performed accurately.

[0044] In addition, the bending guide groove (24) formed in the rod-shaped metal tool (20) and the gripper movement guide groove (46) of the hollow support tube (40) are also formed to correspond to the number of elastic clamps (84).

[0045] Hereinafter, an example of the use of the present invention, as described above, will be explained in detail through the drawings.

[0046] First, the clamp operating plate (110) formed on the hollow handle (60) is pressed in the state before the bolt is grasped (see FIG. 1). Accordingly, the slide plate connecting rod (108) slide plate (104) advances while overcoming the elastic force of the elastic member (106).

[0047] As the above slide plate (104) advances, the elastic clamp (84) of the clamp part (80) formed in the steel hollow tube (88) at the tip of the rod-shaped metal tool (20) opens.

[0048] When the elastic clamp (84) opens, the prepared bolt is grasped using the gripping teeth (82) so that it can be fastened with the rod-shaped metal tool (20), and the force applied to the clamp control plate (110) that was being pressed is released.

[0049] As the force applied to the clamp operating plate (110) is removed, the elastic member (106) formed by the expansion spring expands and retracts the slide plate (104).

[0050] As the slide plate (104) retracts, the steel hollow tube (88) connected to it also retracts in conjunction, and the clamp part (80) at the tip also partially enters into the guide gap (42) formed inside the columnar hollow tube body (44).

[0051] Accordingly, when the elastic clamp (84) of the clamp part (80), which was exposed and in a free state, is pressed by the bending forming part (86) caught at the entrance of the long hollow tube (44), the gripping teeth (82) retract while holding the bolt, thereby firmly gripping the bolt once again.

[0052] As the steel hollow tube (88) retracts, the elastic clamp (84) pulls and wraps around the bolt and is joined to the tip of the rod-shaped metal tool (20).

[0053] In this state, when the bolt is tightened to some extent by holding and rotating the hollow handle (60), the gripper operating plate (110) is pressed again so that the gripping teeth (82) are released from the bolt, making it easier to tighten or loosen the bolt using the rod-shaped metal tool (20).

[0054] As mentioned above, this has the advantage of improving productivity and efficiency when working with a screwdriver, as it prevents bolt detachment even when fastening and loosening operations are performed using a screwdriver equipped with elastic clamps in places where it is difficult to move at heights or where small objects are likely to fall out.

[0055] The embodiments of the screwdriver equipped with an elastic clamp according to the present invention described above are merely illustrative, and those skilled in the art will readily understand that various modifications and equivalent alternative embodiments are possible therefrom. Therefore, it will be readily understood that the present invention is not limited only to the forms mentioned in the above detailed description. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims. Furthermore, the present invention should be understood to include all modifications, equivalents, and substitutions within the spirit and scope of the present invention as defined by the appended claims.
